ZG-HA/ELD Series Bearing Induction Heater

Descriptions
Main features of "ZG-Hitfar" bearing electromagnetic induction heaters:
1. Quick setting of temperature;
2. Real-time temperature display;
3. Automatic over-temperature protection;
4. Automatic heat preservation, etc.
APPLICATION
The bearing induction heaters are mainly used to heat various types of metal
parts such as bearings, gears, bushes, shaft sleeves, diameter rings, pulleys,
shrink rings, connectors, etc. The bearing heaters expand by heating to achieve
interference The need for assembly. Functions include: quick setting of
temperature, real-time temperature display, automatic over-temperature
protection, automatic heat preservation, etc.
The Structure & Working Principle of Bearing Induction Heater
The bearing induction heater is a kind of air-cooling frequency induction
heating device, which is composed of induction heating main control, yoke
steel, temperature controller & sensor and other accessories. The purpose of
heating the bearing is to cause the bearing to produce thermal expansion, so
that the bearing can be smoothly sleeved on the shaft.
In fact, the working principle of bearing heater is applied electromagnetic
induction heating, which is actually the use of magnetic fields. When we put
the bearing on the yoke steel, the circuit is closed and a magnetic field is
formed. The heated work piece is a equivalent to a resistance. The current in
the magnetic field will accumulate every time it passes through the resistance.
As a result, the workpiece is also heated.
The Advantage & Feature of Bearing Induction Heater
- Safe, clean and environmentally friendly
Traditional methods, such as live roasting, oil bath, oven roasting, are not
only costly but also produce coke smoke, odor and waste oil. The application
of induction heaters can replace traditional methods to create a safe and
clean working environment.
- Fast and without damage
After heating, the bearing expanded outward in the cylindrical direction, which
can avoid damage during installation. Induction heating is an excellent heating
method, and it does not need to be preheated. The bearing can be heated to
120°C in a few seconds or minutes without damaging the pre-lubrication.
- Rational design
In order to meet the requirements of the industrial environment, the design
concept of induction bearing heater for sale is modernization, rationalization,
easy operation and high durability. Portable bearing heater is a convenient
heater to facilitate the on-site use.
